12D808 - Walter W-222 Stainless Steel Mounted Grinding Point

Precision Grinding for Stainless Steel Applications

The Walter W-222 Mounted Point (SKU: 12D808) represents the pinnacle of abrasive engineering for precision metal finishing. Designed specifically for the demanding requirements of stainless steel (Inox) fabrication, this mounted point utilizes high-purity abrasive grains bonded in a vitrified matrix. This formulation ensures that the abrasive cuts coolly and efficiently, preventing the heat buildup that often leads to discoloration or warping in heat-sensitive alloys.

The W-222 shape is a standard cylinder measuring 1 inch in diameter and 2 inches in length, mounted on a durable 1/4-inch steel shank. This geometry is particularly effective for internal grinding operations, such as enlarging holes, smoothing the inside of pipe fittings, or deburring machined parts where larger grinding wheels cannot reach. Walter Surface Technologies manufactures these points with strict quality control regarding concentricity and balance. A perfectly balanced point significantly reduces vibration at high RPMs, which not only improves the surface finish quality but also protects the bearings of the pneumatic or electric die grinder being used.

In industrial MRO environments, the 12D808 is an essential consumable for tool and die shops, food processing equipment repair, and general fabrication where stainless steel is the primary material. Its ability to maintain its shape while removing material aggressively makes it a superior choice over lower-grade alternatives that crumble or glaze over quickly. Whether used for blending contours or cleaning up heavy welds in hard-to-access corners, this mounted point delivers consistent performance.
